BICYCLE-LOCK.

SPECIFICATION forming part of Letters Patent No. 599,017, dated February15, 1898.

Application filed November 23, 1897- erial No. 659,549. (No model.)

T0 at whom, it may concern:

Be it known that I, CARL P. R. Sc RoEnER,

a citizen of the United States, residing at Harrison, in the county ofHudson and State of New Jersey, have invented certain new and usefulImprovements in Looking Means for Bicycles, &c.; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

This invention is in the nature of an improvement in the locking meansfor bicycles set forth in my previous Letters Patent N 0. 589,861,granted to me September 14, 1897; and it consists, essentially, in ameansto be used in connection with the movable parts of the lockingdevice, whereby the latter can be permanently attached to the frame ofthe vehicle and when not in use to engage or lock one of thepedal-cranks to prevent the motion of the driving-chain and the turningof the wheel operated by means of said chain is out of the way of therotary movement of the pedal-crank.

The invention consists, furthermore, in the several arrangements andcombinations of parts, all of which will be hereinafter fully describedand finally embodied in the clauses of the claim.

The invention is clearly illustratedin the accompanying drawings, inwhich Figure 1 is a front elevation of my novel form of holding orlocking device in position on the frame of the vehicle and illustratingits holding or looking parts in their holding or locked engagement withone of the pedalcranks of the vehicle. Fig. 2 is a top view of thedevice when detached from the vehicle, the parts thereof beingrepresented in practically their relative positions whenin holding orlocked engagement with the pedal-crank of the vehicle. Fig. 3 is a sideview of the device looking in the direction ofarrow y in Fig. 2; andFig. 4 is a horizontal section of the device, taken on line 00 in Fig.3. Fig. 5 is a plan view of the device, illustrating the relativepositions of the parts when the holding or looking parts are disengagedfrom operarespectively, the plates 0 and c tive holding contact with thepedal-crank, andFig. 6 is aview of the device when looking in thedirection of the arrow 2 in said Fig. 5.

Similar letters of reference are employed in all of the above-describedviews to indicate corresponding parts.

Referring to the drawings hereunto annexed, a indicates thesprocket-wheel on the usual form of crank-shaft in the bottom bracket ofa bicycle or other like Vehicle, and

of the vehicle-frame in the manner set forth in said Letters Patent.

In order to arriveat a better understanding of the construction of thedevice 0 in connection with the new features, I will briefly describethe same. Said device consists, essentially, of a flat band or plate 0,to the opposite ends of which are pivotally secured by means of suitablerivets,pins,or screws cl and d the semicylindrical plates 0 and 0provided with holding loops or eyesc Pivotally arranged between saidloops or eyes of the respective plates 0' and c and on suitable pins 0therein are the holding loops or eyes 0 of a second pair ofsemicylindrical plates 0 and 0 with. which are pivotally connected bymeans of the rivets, pins, or screws d and d Said main plate a and theplates 0 and c are provided with oppositely-placed holes, in which,whenthe semicylindrical plates 0 and c and c and 0 have been placed aboutthe reaches a and a respectively, of the the vehicle-frame, are

arranged certain bolts or screws f, whereby the device 0 can be securelyand permanently fastened in position on'theframe' of the Vehicle. Eachplate a and c has an eye or loop 0 and pivotally connected with certainpins 9 in said eyes or loops 0 are arms 0 provided with slots 0 Slidablyand adjustably con nected with each arm 0 by means of the pin or pins h,movably held and secured in the said slots 0 are a second pair of plateso having the curved parts 0 which are adapted to embrace the pedal-crankwhen the parts are in the positions indicated in Figs. 1 to 4,inclusive, and can be locked in such position by inserting the hasp of asuitable lock 7 through perforations e in the ends of said plates c".Thus it will be seen that the device is readily adapted for holding orlocking the pedal-crank in a fixed position.

hen it is desired to use the wheel, the arms 0" and plates 0 are thrownback into the positions indicated in Figs. 5 and 6 and are locked orheld in such position by a suitable locking or holding means,whichconsists, essentially, of a post 6, rotatively arranged in a hole in themain plate 0, said post having a head or finger piece 6, and c is aspring encircling said post 6 on that part between the said head (2 andthe exterior surface of the plate 0. On the opposite end of said post 6are a pair of wings a which,when the plates or arms 0 and a are in thepositions indicated more especially in Fig. 5,can be brought against thesurfaces of said plates or arms 0 and preferably between a pair of studs0 on said arms to hold them owing to the action of the spring e in suchposition, as will be clearly understood. lVhen the arms or plates 0 andc are to be disengaged from the holding or locked contact with saidwings 6 the post a is pushed against the back of the plate 0, wherebythe wings c on said post can be turned out of engagement with said studs0, and when the post 6 is then released by the operator the spring ewill bring the said wings against the inner surface of the plate 0, asillustrated in Figs. 2 and 4t, and the arms or plates 0 and 0 can beturned from the posit-ions indicated in Figs. 5 and 6 to thoseillustrated in Figs. 2 and 4 to be locked about the pedal-crank of thevehicle.

A cheap, simple, and readily-attachable locking means for bicycles orthe like has thus been devised which is neat and ornamental inappearance and when not in use to lock or hold the pedal-crank in afixed position can be retained in position on the vehicle-frame withoutinterfering with the action of the pedal-crank.

I am aware that changes may be made in the several arrangements andcombinations of the parts herein shown and described without departingfrom the scope of my present invention. Hence I do not limit myself tothe exact arrangements and combinations of the parts described in thespecification and illustrated in the accompanying drawings.
